Making a Color Natural Wood of Thinned Small Diameter Tree and Its Utilization

This study was carried out to make a color natural wood of thinned small diameter tree and of low grade tree impregnated with water born dyes by transpiration. Ascending speed of dyestuffs and the pattern of dyeing along with kind and concentration of dyes. and species of trees were investigated. Furniture and other wood products were made of color natural woods to show the feasible uses of high added value. The results were summarized as follows ‘ 1. The higher concentration of dyes, the faster ascending speed of dyes. Ascending speed of dyes was faster in hardwood than softwood. 2. The color pattern of wood impregnated with dyestuff solution was affected bv anatomical structure of wood species. especially by vessel arrangement type in case of hardwood. 3. Teak color mixed dyes had a bad effect on ascending rate compared with sole dyes. For the manufacture of better color natural wood. it is necessary to develop the appropriate type and color of dyes. 4. Color natural wood has high added value and natural color grain and is very useful for furniture making. interior material. object of art. overlaid material for the laminated wood. etc.. Thinned low grade trees can be used to produce color natural wood. Therefore this result can promote thinning and produce good forestation
